SPRING-HINGE.

Application led March 16, 1914, Serial No. 825,040. Renewed January 16, 1915.

To all whom it may concern:

Be it known that 1, EMiL BoMMnn, a. citizen of the United States of America, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification.

This invention relates to spring-hinges and more particularly to improvements therein so as to provide special devices for the purpose of facilitating' the lubricating of the operative parts on the one hand, and on the other hand, provide advantageous means for locking the parts in position.

The object of the invention is to provide means for this purpose and to do so at aV reasonable cost of manufacture and simplicity in the assembling of the parts.

For this purpose my invention consists of the improved features hereinafter described and finally pointed out in the claims.

1n the accompanying drawing, Figure 1 is a front view of a single-acting springhinge provided with my improved device, Fig. 2 is a corresponding section taken on line 2-2 of Fig. 1, Fig. 3 is a vertical section taken on line 3 3 of Fig. 2, Fig. 4 is a side view of a portion of the pintle having a lug thereon, Fig. 5 is a section of Fig. 4: taken on line 5 5, Fig. 6 is a perspective view of the leaf with an ear having the pintle opening provided with an additional recess to be engaged by the lug of the pintle, Fig. 7 is a perspective view of an improved form of washer used in the coperation of the parts shown in the various figures.

Similar characters of reference indicate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, and more particularly to Fig. 1, a form of well-known single-acting spring-hinge is shown therein, but my invention is not limited in its apnlication to a single-acting spring-hinge. The leaf 10 is provided with the ears 11 and 111, and the leaf 12 is provided with the barrel 13. The leaves 10 and 12 are provided with the usual screw-holes 14 to enable the spring hinge to be attached to the door and door casing by screws or the like. Interposed between the barrel 13 and the ears 11 and 11.1. are the usual spring-holders 15 and 151, and passing through perforations of the ears 11 and 111 of the leaf 10 and the springholders is a pintle 16 which is provided at Specification of Letters Patent.

Serial No. 2,723.

its ends with screw-threaded portions, one

end being clearly shown in Figs. 3 and l, the screw-threaded portion being indicated by 17. The screw-threaded portions 17 are provided with pintle heads or nuts 18 of any suitable shape. A coil spring 19 is interposed between the spring-holders 15 and 151. The parte in so far as have been just referred to are all well-known, and modifications may be made therein in the manner known to those skilled in the art.

To provide improved oiling means for the spring-hinge, the spring-holders 15 and 151 are provided with a depression or recess 2O and interposed between the ear 11 and spring-holder 15 is a washer 21, one form of this washer being shown clearly in Fig. 7, and this is provided with a central opening 22 to enable the pintle to pass therethrough, and with a radial slot 23. The ear 11 is provided with an opening 24 for the purpose of permitting the pintle to pass therethrough, the opening 21 of the ear 11 being provided with an extension recess The pintle 16, which is clearly shown in Fig. 4, is provided near one of its ends with a lug 30, which is forced out of the material forming the pintle so as to have the configuration shown in Figs. 3 and 4i, and clearly shown in crosssection in Fig. 5. By thus forming a portion of the material constituting the pintle 16 to form the extended lug 30, the portion of the pintle adjacent each side of the lug 30, is flattened, as clearly shown at 31 in Fig. 5, and also in Fig. 4. rEhe length of the lug 30 is approximately equal to the combined thickness of the ear 11 and washer 21. The width of the lug 30 is determined approximately by the width of the recess 25 of the ear 11 and radial slot 23 of the washer 21.

"When the parts are assembled, in the manner shown in F ig. 3, the pintle 16 has its lug 30 extending downwardly through the opening 2e and its extension 25 of the ear 11, and through the opening 22 and slot 23 of the washer 21, and preferably protrudes into the depression 20 of the spring-holder 15. The lug 30 is preferably loosely fitted into the recess 25 of the ear 11 and into the slot 23 of the washer 21, which gives a slight amount of play or freedom of movement to the correlated parts, whereby the lubrication is facilitated under the operation of the door. The oil is injected from an oil can or other device, into the radial slot 23 of the washer 2l, and passes along the slot 23 to quicken the passage of the oil into the deiY pression or recess 20, and to the otherparts of the hinge. By the slightmovement of the washer 21 in relation to the lug 30, and its semirotary to and fro movement .upon the spring-holder 15 when the door isoperated, the oil is caused to spread between the washer 21 and the adjacent bearing surface of the spring-holder 15, while the lug 30 aids to distribute the oil along the pintle to the other bearing surfaces of the hinge, so as to obtain the most efficient use thereof. The lug 30 of the pintle 16 gives the -further advantage of locking the pintle in position in respect to the ear 11 and washer 21, whereby the device heretofore proposed to accomplish this purpose, namely, providing the pintle with a hexagonal configuration of a washer having an opening commensu 'ate therewith, as for instance shown in my copending application Serial No. 761,143 and also in my co-pending application Serial No. 825,089, both of which show a hexagonal configuration, is not needed, yet, nevertheless, the advantage of the unitedmovement of the pintle 1G, ear 11, and washer 21 is obtained, and the permanent location of the slot on the periphery of the washer 21, in relation to the periphery of the ear 11 is established, and maintained for convenience in lubrication.

My device is very simple in manufacture, and may be made without entailing any great cost, either in material or services, and at the same time lends simplicity tothe assembling of the parts, and, lastly, insures a very efficient means. v

I have described an embodiment of my invention, but changes may be made therein without departing from the spirit of the invention as defined in the appended claims.

I claim as new and desire to secure by Letters Patentf 1. In a spring-hinge, the combination of a spring-holder provided with a depression, a washer provided with a central perforation and a radial slot extending outwardly therefrom to the periphery of the washer, said slot communicating with the depres sion of the spring-holder, and a pintle having a lug, said lug extending into the radial slot of the washer.- y
